By using a low-head type pile driver and a low-head type special auger in this construction method, it is possible to perform construction with a low head!
The "Low Headroom Double R Method LH-RR Method" enables construction in high N-value layers such as soft rock and gravel with low vibration and low noise using small foundation machinery. Traditionally, ground that required large foundation machinery can now be constructed using a leaderless pile driving machine weighing between 20t and 40t, equipped with a high torque auger ranging from 70.7 to 98kNm, utilizing main body pressure input and a special auger head for hard ground. Additionally, the removal of obstacles and crushing methods underground can also be performed by changing attachments. 【Low Headroom Special Auger Performance (Partial)】 ■ Auger Type: AGD7000 ■ Weight (kg): 1,720 ■ Operating Pressure/Flow Rate: 27.4Mpa・220l/min ■ Base Machine Used: Hitachi Construction Machinery RX2300・SRX2700・RX3300 Low Headroom Dedicated Machines *For more details, please download the PDF or feel free to contact us.
